Measurement device and method for thrombus elasticity

Abstract

The invention relates to the technical field of medical equipment and particularly relates to a measurement device and method for thrombus elasticity. The measurement device for thrombus elasticity comprises a driving module, an adjustable constant-temperature module, a testing cup, a testing needle, a reflection mirror and a moving device, wherein the adjustable constant-temperature module is arranged on the driving module and is connected with the driving module; the testing cup is arranged in the adjustable constant-temperature module; the testing needle is arranged on the testing cup; the reflection mirror is fixed on the testing needle; the moving device is connected with the reflection mirror; the adjustable constant-temperature module is used for heating or cooling the testing cup. The measurement device for thrombus elasticity further comprises a laser device, a PSD (Position Sensitive Detector) position sensor, a data processing module which is electrically connected with the PSD position sensor, and a man-machine interaction module which is electrically connected with the data processing module. According to the measurement device and the measurement method provided by the invention, an optical lever principle is used for measuring thrombus elasticity and the influences caused by the measurement with an electromagnetic sensor are eliminated, so that the measurement precision is improved. The adjustable constant-temperature module is used for adjusting and controlling the temperatures of experiment samples, so that the influences of an environmental temperature during blood clotting can be really simulated, and the accuracy of measured data is improved.

Description

technical field [0001] The present invention relates to the technical field of medical devices, and more specifically, to a thrombus elasticity measurement device and a measurement method thereof. Background technique [0002] Abnormal coagulation function is a common symptom in clinical practice. Timely, effective and accurate measurement of blood coagulation ability of patients plays an extremely important role in surgery and clinical operations. [0003] The current instruments for testing blood coagulation characteristics use simple mechanical movements to simulate the natural flow of blood in blood vessels and arteries in living bodies. Induced in a low-shear environment (similar to slow static blood flow), changes in blood viscoelasticity, ie changes in thromboelasticity, are detected. Thromboelastography is widely used in surgery to detect coagulation function and guide blood transfusion and treatment. It can realize rapid diagnosis, guide treatment and judge curativ...

AI Technical Summary

Problems solved by technology

At present, most thromboelastography instruments use electromagnetic sensors to measure thrombus elasticity, and the price of the sensors is high

The limitation of the current thrombelastograph is that the detection of thrombus elasticity is carried out under the condition of 37°, and some operations, such as cardiovascular surgery, often adopt a hypothermic environment, so the current thrombelastograph cannot monitor Therefore, it cannot reflect the real coagulation status of the patient
